EDGING DEVICE.

SPECIFICATION formingpart of Letters Patent N0. 707,641, dated August26, 1902. Application filed March 30, 1901. Serial IIo. 53,685. (Nomodel.)

T0 at whom, it may concern:

Be it known that I, JOHN ROSTOOHIL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented a certain new and useful Improvement in Edging Devices, ofwhich the following is a specification.

My invention relates to means for edging lumber.

The objects of my invention are the provision of a simple, effective,and easily-Opel ated device for holding and moving a board across thetable of an edging-saw, to permit quick and accurate adjustment of theboard in place upon the table, to insure against displacement of theboard, to make it unnecessary to move the board more than once acrossthe table in order to secure a straight edge, to permit of considerablevariation in the length of the boards'without necessitatingreadjustments of the means for holding or gripping the boards, to permitof considerable variation in thethickness of the boards, to provide anedging device which is readily adjustable with respect to boards ofdifferent lengths, and to provide certain details and features ofimprovement tending to increase the general efficiency, and therebyrender a device of this character satisfactoryand serviee'able.

To the foregoing and other useful ends the device may consist of a slidehaving dogs adapted and arranged to engage the ends of a board or pieceof lumber. In accordance with the aim of the invention one of these dogscan be mounted for a sliding adjustment along one end portion of theslide, and the other dog can be pivoted to the opposite end of saidslide. The purposes of the invention can be further attained by adaptingthe pivoted dog to engage the upper surface of the board and also bygiving this dog the additional function of a handle or grip byv which tomove the slide. The nature and advantage of my invention will, however,hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a plan of a saw-table providedwith an edging device constructed in accordance with my invention. Fig.2 is a longitudinal section on line a: so in Fig. 1. Fig. 3 is acrosssection on line 1 7 in Fig. 1. Fig. dis a front view of the pivoteddog. adjustabledog.

' It will be understood, that the saw A and table B can be ofanysuitable or desired'form andconstruction; r

The slide C is preferably adapted to slide in a channel iron D. Thischannel-iron can be sunk in a slot or groove in saidtable. Said 'slideis preferably somewhat longer than the lumber to be edged and isprovided on its upper surface with a dovetail groove 0, which extendsfrom its forward end along the greater part of its length. The forwarddog E is mounted for adjustment along the groove 0, so as To accommodateboards of difierent lengths. A set-sorew 6 can be employed for lookingor securing the dog at any point in said groove. This dog is preferablyprovided with an inclined or overhanging face 8, which is preferablyformed withserrations or sharp ridges and which bites or holds theforward end of the board 1. The dog F is pivoted to the rear end of theslide. This pivoted'dog is preferably formed witha handlef/ The edge fof the pivoted dog may be provided with teeth, so as to .enable it tomore firmly and effectively engage the upper surface of the board. Thepivotal point f is preferablylocated in such manner that the Weight ofthe hand will at all times hold the dog in firm contact with the board.In this way the dog is adapted to serve as a handle or grip by which tomove the slide forward Fig. 5 shows an and back in its guideway; Ifdesired, the dog can be adjust-ably mounted upon the handle or'lever, asshown in Fig. 5. With this latter arrangement the dog can'be readilyadjusted with respect to different thicknesses of lumber. If desired,the dog can be provided with a gage f. It will be seen that theformation of the pivoted dog permits of considerable variation in thelength of the boards without necessitating readjustment of the dog E.

Thus constructed the operation of my invention is as follows: The board1 is'adjusted in place as shown in Fig. 2, the operator grasping thehandle f with his left hand and the gage f enabling him' to readilydetermine the proper position for the board. When the board is properlyadjusted in place, the operator moves the slide forward, so as to passthe saw through the edge of the board, or

edge it, as the operation is termed. In moving the slide forward theoperator, as previously stated, grasps the handle f, and the weight ofthe hand keeps the dog F pressed firmly down upon the board. .This isalso true in drawing the slide back, as the formation or shape of thedog E and its handle is such that the backward pull on the handle can beaccompanied by a downward pressure of sufficient force to prevent thedog from rising from the board. In this way both the gripping of theboard and the movement of the slide are eifected through the medium of asingle device. Furthermore, the board is held firmly in place, whetherthe slide is advancing or moving back. If the saw is to'be employed forpurposes other than edging, the dog E is removed and the dog F thrownback and allowed to hang down, so as to be out of the way.

What I claim as my invention is 1. A device for edging lumber,comprising a saw and saw-table, a slide arranged for forward-and-backward movement in a way extending alongside said saw, a dogor jaw mounted for sliding adjustment along the forward portion of saidslide, a dog pivotally connected with the rear end'of said slide andadapted to extend forward and engage the upper surface of the lumber,and an upwardlyextending handle rigid with said pivoted dog and adaptedto aiford a grip for moving the slide in both directions withoutreleasing the lumber, substantially as described.

2. Asaw-slide, adog slidably mounted upon said slide, a rear pivoted dogadapted to engage the upper surface of the lumber, an upwardly-extendinghandle rigid with said pivoted dog, the pivot of the latter beinglocated back of a line extending lengthwise through said handle, so thatwhen force is exerted upon the handle for moving the slide back andforth it will be imparted downwardly to the pivoted dog and hold same inengagement with the lumber substantially as described.

3. A saw, a slide, an upright handle pivoted to the rear end of saidslide, a dog slid ingly mounted upon said handle and provided with meansfor rendering it rigid with said handle.

4. Asaw, a slide, forwardly-adjustable dog,

rear pivoted dog engaging the upper surface of the lumber, the pivoteddog being attached and so formed as to provide space between itsengaging point or end and its pivot, so as to admit of variation in thelength of lumber without necessitating readjustment of the forward dog,and an upwardly-projecting handle rigid with said pivoted dog andaffordinga grip for moving the slide back and forth, said handleextending in a line forward of the pivot for the jaw, so that when forceis exerted upon the handle for moving the slide back and forth it willbe imparted downwardly to the pivoted dog and hold same in engagementwith the lumber, substantially as described.

5. In a lumber-edging device, a saw-table, a slide fitted in a wayformed in the table,a jaw on the slide forming a member of the clamp,said jaw having an undercut edge facing the opposite member of the clampand into which the ends of the boards are seated, a set-screw extendingthrough the block and engaging the slide, a' clamping-dog pivotallyconnected with the slide, said dog having an engaging edge formedtherewith, a suitable distance forward of the pivot and a handleextending upwardly and forward of the pivot of said dog, whereby theforce used in manipulating the slide can be utilized simultaneously tomaintain the dog in engagement with the ln mber, substantially asdescribed.

6. In a lumber-edging device, a saw-table, a slide fitted in a wayformed in the table, a jaw on the slide forming-a member of a'clamp,said jaw comprising a block having an undercut edge facing the oppositemember of the clamp and into which the ends of the boards are seated, ascrew run through the block and seated in the slide, a clamping-doghaving its end pivoted to the slide, said dog having an engagingmem berformed therewithadistance from the pivot and a handle extending upwardlyand forward of the pivot whereby the force used in manipulating theslide can be utilized simultaneously to maintain the dog in engagementwith the lumber, substantially as described.
